Application led November 3, 1911. Serial No. 658,314.

To all whom it may coificern:`

Be it known that I, HENRY J. KEMPF, a citizen of the United States of America, residing at Springfield, .in the county' of Hampden and State of Massachusetts, have 4inrented new and useful Improvements in Wrapping-Machines, of which the following is a specification. v

Thisinvention relates to wrapping ma chines and has especial reference to the wrapping of confections, and the like, in wrappers folded about the article in one d1- recticn, the ends of the wrapper then being twisted to close the same, as distinguished from that type of wrapping machines 1n which the ends of the wrappers are folded over or against the ends of the article. Cer- *tain features of the invention however can be applied to the second type of wrapping machines mentioned.

The object of the present invention is to provide a, machine `to which the confection may be fed in a plastic mass, cptting and rolling means being provided to divlde the mass into pieces of proper shape and size, which pieces are first compressed and then inclosed in wrappers cut from a roll of wrapping material fed into the machine, all as hereinafter fully described and pointed out in the claims. The machine is constructed and arranged so that after the pieces of candy or articles to be wrapped are fed to the machine said articles are substantially compressed or mechanicallyshrunk before the wrapping operation is completed. In wrapping articles of certain classes it is im portant to thus mechanically shrink each article before it is completely wrapped. For instance in wrapping molasses kisses by the ordinary methods the confection shrinks after it has been wrapped and kept for any length of time. The wrapper then looks crumpled and the confection looks stale .rendering it unsalable. These same articles as wrapped in applcants machine are me chanically shrunk before being wrapped. They can not ordinarily shrink any more. Therefore when the wrapper is properly placed around the article each Wrapped piece will have a plump fresh appearance making it salable at all times. While applicant prefers to compress the article when it is partially Wrapped and then complete the Wrapping operation it in am that the l Figure 1 is a side elevation of one side of the machine showing, in a general way, the relation of the confectionery feeding devices and the roll of wrapping material to each other and to the packing -mechanisnu Fig. 2 is a side elevation of the opposite side of thcl machine in which the means for twisting the ends of the wrapper and the ejection of the wrapped article are clearly shown in their relation to the carrier-wheel in the peripheral pockets of which the articles are received for wrapping, and transferred from one part of the machine to another. Fig. 3 is a plan View of the top of the machine as it would be projected over from Fig. 1. Fig. 4 is an end elevation of the machine looking at the left-hand end of Fig. 3, this and the preceding figures all being on the same scale. Fig. 5 is a cross sectional view on an en larged scale on line 5-5, Fig. 3, showing, in elevation, the carrier-wheel and means for feeding confections thereto, and also shows much of the operating mechanism of the machine. Fig. 6 is a sectional elevation, also on an enlarged scale, showing the construction of the feeding devices for the strip of wrapping n1aterial,-the plane of this section being on line 6-6, Fig. 3. F 7 is a cross sectional View of the mechanism shown in Fig. 6, taken on line 7-7 of said last named figure. This View shows the relation of the cutting devices to the feed-rolls for the wrapping material. Fig. 8 is a sectional elevation ,in the plane of line 88, Fig. 3, showing the means for feeding the confectioner material into the machine and cutting the same into suitable uniform pieces. Fig. 9 is a sectional elevation in the plane of line'9-49, Fig. 3, showing the construction of the mechanism for graspling and twisting one end of a wrapper. T is mechanism is duplicated for the opposite end of the wrapper, the two working in unison. The device used for opening and closin the jaws of the twisters is also shown in tlis view. Fig. 140 is a sectional elevation on the line 10H10, Fig. 3, at right angles to the section shown in Fig. 9, and illustrating more particularly the intermittent driving mechanism for the twister jaws,

Referring now to the general views of the machine, (Figs. 1 to 4t inclusive) the confectionery stock is fed into the machine over a table a between toothed grooved rollers b and c (shown in Fig. 8 particularly), whereby it is reduced to the proper dimensions, these feed rollers being rotated by a suitable train of gears d shown in Figs. l and 3. e is the web of wrapping material from which the wrappers are cut, this being drawn off from a reel As shown in' Fig. 3, the wrapping material and the confectionery move one toward the other and meet at a point opposite the periphery of the carrier-wheel g, all of which is clearly shown in Fig. 3. g is used to designate the carrier- Wheel only in a general way as it is composed of a number of working parts which will be referred to separately. As shown in Fig. 5, this carrier-wheel g is provided with equally spaced peripheral pockets z. extending transversely across the wheel, each pocket having one movable side 7c in the form of a plunger and actuated by an elbow-leverfml pivotally supported on the side of the carrier-wheel g,#on,e arm of which lever is engagedby a camlo to ed'ect the withdrawal of the movable side of the pocket just referred to, against the tension of a spring p which spring serves to compress and hold a piece of confection r in the pocket. This carrierwheel is rotated stepby-step in time with the operation of the cutting device which cuts ofi' a piece of confection from the strip fed down from the pair of grooved rollers c through a tubular member s beneathrsaid rollers (see Fig. 5),

and across the bottom of which member the knife t is reciprocated, as shown in Fig. 8, a piece of confection 1- being indicated in that figure as just cut off from the piece of stock o. A block t1 is screwed to the frame opposite the cutting edge of the knife and has a slot t2 in it for the edge of the knife to enter. This block thus backs up the stock and prevents a thin edge of confection from followin the knife edge on either side,- which t in edge may harden and subsequently cut through its Wrapper. A spring scraper t3 is placed beneath the knife t to keep the beveled edge of the latter free from any stock that may stick to it. rlhe upper side of the knife clears itself,-all of which is shown in Fig. 8. Referring still to Fig. 5, e 1s used to distinguish the wrappers as well as the web from which they are cut olf, and in this gure the wrapper cut from the web is shown in its relation to the periphery of the carrier-wheels and the position of a piece of confection just cut od and forced into one of the pockets of the wheel by a plunger fw which has a sliding'movernent beneath the member s and toward one of the ocketsA in the carrier-wheel, the wrapper e aving been moved to a position opposite the mouth of the pocket, by means of the feed-rolls shown in Figs. 6 and 7, just 1n advance of the movement of the piece of confection'into the pockets. The two metal guides ai afford means to support the wrapper in proper position in front of the pocket,

`the plunger w moving through the space between these guides forcing the confection against the central part of the wrapper into the pocket and covering three sides of the confection, leaving two flaps 3 and 4 to b e folded over the article in the usual manner. During the pause of the carrier e for receiv# ing a piece of confection in the pocket, immediately after the plunger fw retires, the flap-folding plate 5 is operated to'swing its edge across the mouth of the pocket 'and thus fold the flap l over the confection in said pocket, whereupon after the return of said flap-folding plate, or at about the same time, the cam 0 is given a slight. n'i'ove ment contrary to the direction of rotation of the carrier-wheel, whereby the elbow-lever m is released from restraint and its spring which is designed to have sufficient strength for the purpose, forces the movable sidc it' of the pocket toward ythe confection 1 substantially compressing the same,land at this time, this pocket is carried by the movement of the wheel under the end of the concentric folding plate 6, whereby the remaining flap 3 of the wrapper is folded over the flap 4, the plate 6 serving, (owing to its position close to the periphery of the wheel,`) to hold the folds of the wrapper in place. The object ofcompressing the confection after its insertion in the pocket is to prevent its subsequent shrinking, whereby it becomes loose in its wrapper. This is an important improvement in the art. rllhe degree of compression is sufficient to positively shrink each article sufficiently to prevent any further considerable shrinkage after the article is wrapped. This is indicated in Fig. 5 by the size of the-piece partially wrapped which has just been put into a pocket by the plunger fw compared to the size of the pieces in all the other pockets which lhave all been mechanically shrunk by thel compression plunger 7c located in each pocket. It will be obvious from a consideration of Fig. 5 that the cross dimension of each pocket in the carrier wheel must be somewhat larger then the cross dimension of the article when first put in the pocket. This is necessarily so because when the article is compressed by the compression plunger c it expands somewhat along its cross dimension not sufficiently however to obviate the compression e'ect in the article. After the compression has taken place the article has approached the same cross dimension as the pocket. lf these dimensions did not correspond the ends of the wrapper would not be properly made.. The article is therefore wholly conlll@ Lemans tained in the pocket both before and after the shrinking operation. It Will be understood that the Wrapper is of such width that its ends may extend far enough beyond the ends of the article incloscd by it to be grasped by the twister jaws 7 when the carrier-wheel has brought the confection into proper position between these jaws, the twisting of the ends of the wrapper taking place at a point substantially opposite that at which the confection is fed into the pocket.

The various movements of the devices hereinbefore referred to and the proper timing thereof are effected by various cams and gears to be referred t0 later, carried on the three principal shafts of the machine, viz., the carrier-wheel shaft 8 and the two main cam-shafts 9 and .10. The drivingshaft 12 isshown in Figs. 1, 2, 3, and 4, and by a pinion 13 on this shaft `(see Fig. 1) movement is imparted to the cam-shaft 10 through the gear 14 in mesh with said pinion, and a gear 15 on the cam-shaft 9 in mesh with the gear 14. To avoid confusion, reference should now be had to Fig. 4, whereinit will be seen that the axis of the shaft 9 is in thesameplane,horizontally,asthestud 17 which, in Fig. 1, appears to be the same as the shaft 9: Fig. 4, however, shows that the stud 17 carries the star-wheel 18 of the ordinary so-called Geneva train, of which the .operating wheel 19 is located on the shaft 9, and on the stud 17 is a gear 20 which, through an intermediate gear Q1 and a gear 22 on the carrier-wheel shaft 8, imparts intermittent movements to the shaft 8 `on which the carrier-wheel g is mounted.

Referring to the movements of some of the parts shown in Fig. 5 andheretofore referred to: the plunger ao, which forces the pieces of confection into the pockets of the carrier-wheel, is actuated by means of the pivotally connected levers E23 andft, the free end of the latter being supported on the rocking arm 25 at the juncture of which with said lever 2t, the latter engages with the groove of the face-cam 26. shown in Fig. 2. The folding blade which effects 'the first fold of the tlap it, is, as slmwn in Fig. 5, carried on an arm .27 swinging on the shaft 8 and actuated by the arm 23 pivotally connected thereto and engaging :r

cam on the shaft S). Thel cam o on the shaft 8 (which, as described swings freely there on) is given an oscillatory movement in either direction, at the proper time, to release the elbow-lever fm, and allow the pinnger le, which constitutes the movable side of the pocket, to engage the confection; this cam being actuated by means of the arm :'29 pivotally connected `to another arm 30, eittendin' from the hnb o'l" the cam o. the arm 29 havingr a stud and roller thereon, indicated by 3l, in engagement with a Ln ear on the shaft 10. The paper-feeding mechanl sm shown in Figs. 6 and 7 is driven intermittently by a broken gear 33 on the shaft 9 meshing with the pinion 34 fixed on the shaft carrying one of the feed1olls which are indicated by 35. These feed-rolls have their shafts geared together, as shown in said Fig. 6, to rotate them in the proper direction--one of the shafts. indicated by 36, being pivotally supported in its frame at 37 to swing away from the opposite shaft, in order to permit the wrapper material to he .freed therefrom, should the web from which the wrappers are eut become jammed between the rolls, as sometimes happens. The shaft 3G is held in proper operative relation to its opposite shaft by means of a limiting lever 38. For the purpose of stopping the feed of the rolls at any time, the broken gear 33 is .held in driving engagement with the shaft 9 by means of a v clutch operated by the arm i10.

Referring now to Figs 5 and 3: as previously stated, the candy stock comes down through the collar s onto a table across which the plunger w has a sliding movement, as described, and t0 position the piece of material which is to be moved by the plunger, an arm 4l is provided which extends up through the table and has a forked end, indicated in Fig. 8 by 42, one of the ends of'the fork being shown therein only in dotted lines behind the piece of confectionery r which has just been cut oft'. The arm 41 is given a vertically reciprocating movement through the table 113 at the proper time to be in position to receive and position the piece of stock r, and it then retires through the table while the plunger Aw moves this piece forward into the pocket of the carrier-wheel. rThe arm 41 is given its proper movement. by means of the camoperated lever 44, shown in Fig. 5, which is operated by the double heart cam i6 shown in said figure. in dotted lines. The arm 41 is jointed. as shown. to give it a free vertical swing, and is moved in one direction by the spring 417. 'lhe lever ll-l is pivoted on a part of the frame at #l-h. .'l'his double heart-cam iti has another function whereby,

by means of' a cam-moore in its side, (not .shown in the draningsQ the ejector arm fit) is actuated. 'this arm has a forked end 50 which may be seen in Fig. the two ends ci' the fork lying on either side of the pocket of the carrier-wheel wherehy. as soon as the piece of contention at this point completely inclosed in its wrapper is released. by the retirement ol.' the `momble side of the pocket, due to the engagement of the elbow-lever ni with the cam o. the forltcd end of the ejector-arm engaging the twisted ends of the wrapper will force the article out ol the pot-.het into the trough 51 wherehy it will he conveyed to some point. onttiti side the machine. rllhis ejector-arm is necessitated owing to the nature of the material handled, since a small perforation in the paper which would permit any of the confection t0 be forced through it, would cause it to stick to the side of the pocket.

.There remains to be described the mechanism for twisting the ends of the' wrapper. which mechanism is shown in Figs. 9 and l0 on an enlarged scale, and in Fig. 2 ou a smaller scale, in which their relation to the ported at 58 in a swiveled head 59, each of' the jaws being provided with inwardly extending arms 60 which enter a slot in the head of a shaft 61, which shaft has an endwise movement through the head 59 and through the pinion 62,whereby said head 59 is rotated. lntermittent rotation is imparted to the pinion 62 and the jaws 7, which rotate therewith, by the train of gears 63, 64, and 65. the latter being in mesh with the gear 55, the gear 64C being pinned to the side of the gear 65, and the gear 63 being merely an intermediate. rlhe swiveled head 59 is hung on trunnions between a couple of arms 66, as shown in Fig. l0. "Whenever the gear 65 runs od the teeth of the broken gear 55, the jaws 7 of the twister will always come to a stop with their ends open, these ends being positioned respectively directly above and below the end of the wrapper to be engaged, thereby. rl`he jaws are opened by means of a cam-arm 67, shown in F ig. 9, which lis pivotally supported between its ends on the frame, the upper end bearing against the end of the shaft 6l and its lower end being provided with a roller which bears against a face-cam 68 which consists merely of a strip of metal secured to the edge of the gear 55, in such position. that just before the teeth of the gear engage the gear 65, the roller on the arm 67 will run oft" the cam 68 and allow the spring 69 to throw the shaft 61 in a direction to close the ends of the jaws 7 against the ends of a wrapper which at that time will be positioned between the jaws. rlhe jaws 7 do not quite come together against the wrapper but in their operative position are spaced apart slightly, as shown in F ig. 9. '.l he ends of the wrapper are practically fiat tubes when grasped by the jaws, and as these ends are shortened, by

noventa twisting, they can draw through the jaws without tearing. This improvement is important since it does away with the necessity of providing means to allow the jaws to approach the ends of the confection during the twist-ing ope-ration, which is necessary when the wrapper ends are grasped tightlyby the jaws. As soon as the jaws have gripped the wrapper, they are given a cer tain number of turns, (determined by the number of gear teeth on the gear 55), whereupon the twist having been put into the ends of the wrapper, another cam-plate 68 on the gear 55 will engage the armv 67 and force the jaws 7 open. At this moment, the carrieri wheel makes another step forward moving the article just wrapped toward the ejector devices and bringing another article between.

the jaws 7 ready for another operation.

rFhe knife (Figs. l and 8) which cuts the confectionery stock into suitable pieces, is actuated by an arm 70 pivoted to the frame at 7l, which arm has a roller 72 there! on engaging the cam-groove 73.

its has been stated, the web of wrapping material e has an intermittentgfeed movement into the machine by means of the rolls 35 already described, and a piece of this material is cut olf from the web of the length required to wrap each piece of confection cut off. from the stock, the wrapper being severed from the web by means of a knife (see Figs. l and 7), which has a swinging movement across the face of a steel plate 76 (Fig. 7) which movement is imparted thereto by a rock-shaft 77 (see Figs. l and 6) having on one end an arm 78 to which the knife is secured, and on the other end another arm 7 9 connected with an arm 80, (shown in Fig. 6 on an enlarged scale,) and which is pivoted to the frame at 81, th lower end of the arm extending down back of the hub of the broken gear 83, where it engages a cam projection, not shown, which at the proper time imparts movement to it, which, in turn, swings the roclrshaft- 77 to act-nate the knife 7 5.

Referring again to Figs. 6 and 7 it will be seen that above and below the feed-rolls 35 are arranged guide-plates for the web e which entend out beyond the rolls in parallel relation thus providing a narrow passage through which the web must pass, the upper and lower part of the plates (all indicated by 76) being secured together by any suitable means. rlhese bars are secured at their extremities to the upper and lower members of the tl-shaped frame in which the feed-roll shafts are mounted and clearlj1 shown in Fig. 6.

Another important mechanism is shown in 9 and 5, and that is the ejector arm 85 pivotally supported at 86 on the bottom frame-part, and which is given a swinging movement beneath and transversely of, the

carrier-wheel by means of a cam projection 87 on the cam-wheel 26, thle upper end of the arm being so timed that it will sweep through the pocket which has last passed the point where the ejection of the confection from the pocket takes place. As stated above, the ejection is effected by the forked arm 49 engaging the twisted ends of the wrapper extending beyond each end of the Docket, but if for any reason this ejection should not take place the confection would be carried around to the feeding point and then the attempt to force a new piece into the pocket would result in the disabling of the machine. The application of the arm 85 to the machine makes such an accident impossible, and is of great value in totally preventing the'damage to the machine above referred to.
